As soon as Yvonne Strahovski, the actress who plays Sarah Walker on the NBC series “Chuck,” walks onto the show’s set on the Warner Bros. lot, every eye is focused on her left wrist.

Strahovski is sporting a huge bandage. It covers most of her hand, her wrist and part of her forearm.

Production on the second season of the spy series has been at full tilt. And in the show, Strahovski plays a spy who has to go undercover to protect Chuck (Zachary Levi), a member of the Nerd Herd at a massive electronics Buy More store. Chuck has had volumes of government secrets implanted in his head.

The logical leap is the Australian actress hurt her hand while doing a stunt with a speeding car, crazed ninja or in some form of hand-to-hand combat.

“This is just a pulled muscle in my wrist. It’s fine,” Strahovski says. When pushed about what action sequence caused the injury, Strahovski smiles and adds, “It is from reaching into my handbag at an awkward angle.”

She laughs and then says that isn’t a great story, but it is the truth.

It is really amazing she has not been hurt while filming the action-filled show, which has been picked up for the entire season. In an episode to air later this year, Strahovski’s character gets into a battle royal with a nemesis from high school, played by Nicole Richie. The fight occurs in a girls’ locker room shower.

“Actually, that was really an easy scene to film,” Strahovski says. “Nicole has a dance background so her choreography skills were really great.”

The actress did get a little help from wardrobe. Her character often has to fight while wearing an evening gown or in high heels. That wardrobe is adjusted – skirts cut, heels shortened – to make it easier to move.

During the first season, Strahovski’s undercover job was at a hot dog stand. She changes jobs this year.

“I think the boys liked the hot dog stand wardrobe more than I did. I won’t tell you what the new job is, but I like the color scheme better,” Strahovski says.

McMahon’s finances rapped up Ed McMahon has an unexpected new job title: rapper.

The 85-year-old former “Tonight Show” sidekick will star in two viral rap videos for FreeCreditReport.com, a financial Web site owned by credit bureau Experian. The videos feature McMahon wearing a tracksuit, being chauffeured around Los Angeles in a Cadillac Escalade golf cart and waxing lyrical about his very public financial troubles.

“I knew I could sing the blues, but I didn’t know I could rap,” McMahon said Wednesday.

The videos will appear online in October.

Charles Harris, FreeCreditReport.com’s vice president of strategic marketing, said the company sought out McMahon to star in the humorous spots after seeing him openly discuss his finances on “Larry King Live.” Harris said McMahon represents “a man who is taking charge.”

In the first video, McMahon – who once pitched the American Family Publishing sweepstakes – and a bodyguard are cruising through a neighborhood looking for sweepstakes winners to ask for some money back, but McMahon doesn’t actually go through with it. In the second spot, McMahon dons a new suit after undergoing a financial and emotional makeover.

“When I retired, I was famous,” McMahon raps in the video. “I had money and glory/I bought a house for 6 mil/I thought nothing could touch me/Until my credit went south, and debt started to crunch me/Next thing I know, instead of playing gin rummy, I was scrambling just to make ends meet/It wasn’t funny.”

After being joined by two scantily clad women, McMahon continues: “Got a bump from the media chumps, but that was temporary/Wife with bad credit was scary, so I got wise/I may have fallen, but I got back up/Now I’m back on the attack, like a ninja swinging nunchucks/I told the haters, `Go on, take a hike’/It’s my show now, and I can do what I like.”
